The PREEMPT_RT patchset does not use do_softirq() function thus trying

Choose some other visible function for the test.  The function does not
have to be actually executed during the test, because it is only testing
filter API interface.

Notes:
I understand that the failure does not exist on mainline kernel (only
with PREEMPT_RT patchset) but the change does not harm it.


Steve,

Would you like me to take this through linux-kselftest next for 5.18-rc1

I am guessing there is no urgency on this - of not I can take this in for
rc5.

thanks,
